Tertius Stele
Physics - Atoms
1) Man has always made use of physics: making tools and using them. As Homo sapiens developed they would have taken with them the talents of their predecessors which included using sticks, rocks and bones for weapons and utensils. These ancients would have learned the simple lessons from nature all around: damn building from the beaver, home making from the birds and the bees, and the convenience of cave dwelling and den making from even the wolf. The production and use of tools, clothing, levers, wheels, fire and smelting developed hand in hand with progressively more sophisticated tribal traditions. One generation passed knowledge of physics to the next, expanding on their primal instincts for food gathering, nurturing and safety, improving communication skills, developing specialization of labor in families and competing to create hierarchies of leadership.
Security and conquest, based on the instinct for survival, were strong motivating forces. Then, as well as now, this base animal instinct gives rise to ever more forceful and effective weapons; this necessity, being the mother of many inventions and developments, led to the expansion of Physics. Those who mastered more Physics, first, were victorious and dominant; the bow and arrow being a more sophisticated weapon than the spear. Today the "Super Power" is the nation with the most lethal toys; they can bring to bare the most sophisticated understanding of Physics.
2) "In true karma-yoga, or the life of perfect action, there is a proper adjustment between the material and the spiritual aspects of life...The mind is not allowed to be immersed in the material life of gnawing wants, nor is it allowed to be merged in spiritual bliss. It is used to face and tackle the problems of life from the point of view of spiritual understanding...The spirit must and ever will have an inviolable primacy over matter; however, the primacy is not expressed by avoiding or rejecting matter but rather by using it as an adequate vehicle for the expressions of the spirit...a musical instrument is valuable only if it gives expression to the song of a musician and becomes a hindrance if it does not yield complete subservience, matter is valuable if it gives free and adequate expression to the creative flow of life and becomes an obstacle if it interferes with it." (Meher Baba, Discourses, 1967)
Taming "matter" is, in part, the job of physicists. The "music" we make and the culture we create surrounding our use of matter--the "expression of the song"--is determined by how well we use our knowledge, and that is everyone's responsibility. There is a real risk that our technology will swallow us like the proverbial snake that eats its own tail until it disappears.
3) Johannes Kepler is often considered the father of Physics, considering his development of the first three "laws" of planetary orbits. The first law reveals that all planets follow an elliptical orbit around Sun.
The second "law" shows that the orbital velocity of each planet increases when it is closest to Sun. Thus if one charts the motion of Mars over a period of one month when it is far from Sun, the thin triangle inscribed with Sun will be equal in area to that of any other one month triangle in any other region of the orbit.
The third "law" is somewhat more complex; the cube of the semi-major axis (half the long axis) of each planet's elliptical orbit is proportional to the square of the planet's orbital period.
Modern Astronomy is populated by physicists since learning about atomic
particles, gravitational forces, magnetism and thermo-nuclear dynamics is
achieved
both in the laboratory of Universe and in the experimental laboratory.
4) In the 21st century, as we will see, the study of physics is the study of
paradox
and often confusing, counter-intuitive theories. Physicists, by the 14th
century, had
grown accustomed to certain basic ideas concerning the way things move.
There was
an invested faith, or "paradigm," relating to motion and optics that
eventually became
described as "Newtonian" or the classical mechanical picture of matter in
motion. This
picture described motion as a continuous blend of changing positions. The
object in
question, whether light or a falling object, moved in a flow from one point
to another. 5) Isaac Newton (1643-1727) came into a world already benefiting from the
new
scientific discoveries of Kepler and Galileo; water power and navigation
thrived, making
life more comfortable. Aristotle and Euclid were still authorities and the
method of
natural philosophy established by Greeks was still prominent. The most
intellectual
people were accustomed to seeking solutions to their problems by speculating
(i.e.,
Descartes), by meditating, and by pondering rather than by experiment,
observation, or
measurement. The problem with this logic, however, is that a priori reasoning can spawn
quite
different answers all with the same legitimate claim to having been
developed by "pure
thought," as if that by itself was a virtue. The only answer more perverse
than one that
comes from pure thought is one that is given by a beneficent god through the
power
structure of a religious hierarchy. Experimentation, it was thought, is
trivial, a rather
pedestrian proceeding with which thinkers need not concern themselves; these
experiments are just as likely to be misleading. Now we know better. 6) Greek philosophers were interested in finding causes; they wanted to know
what
matter is and why it behaves as it does. Even so, it was Galileo Galilei
(1564-1642)
who was the first man to have a clear notion about inertia, the first to use
the telescope to look at the night sky,
but not the first nor the last to have been persecuted by religious
authority for his
pragmatic creativity. It is a sad irony of humanity that the most artistic
expression of
wonder and most sincere celebration of the mystery of Universe comes from
obdurate
religious beliefs that even in the most advanced societies became a barrier
to scientific
study and discovery. 7) One of Newton's greatest achievements was to explain the movement of
heavenly bodies on the basis of laws of motion and of universal gravitation,
improving
on Kepler's ideas. He developed laws of motion that governed the movement
of both
earthly and heavenly bodies. Newton was a devoutly religious man, however,
and in
many ways a mystic. He did not believe that religion or mystery had
anything to do with
the mathematical laws of planetary motion, although they had to do with the
First
Cause. "Such a wonderful Uniformity in the Planetary System must be allowed
to Effect
of Choice..." that is, it must be admitted to come about by design and not
by chance
(more on this later).
8) Shortly after the founding of The Royal Society of London for the
Promotion of
Natural Knowledge in 1660, Newton became a member and eventually (1703) the
President. The Royal Society took as its motto: "We don't take anybody's
word for it."
This organization sounded the death knell for the Aristotelian method and
body of
science. Newton became the standard barer for the objective approach to
science
through experiment and the rigorous testing of hypotheses. Early in Newton's career he stated: "...the Theory, which I propound, was
evinced by me, not by inferring "tis thus because not otherwise, that is,
not by deducing
it only from a confutation of contrary suppositions, but by deriving it from
Experiments
concluding positively and directly." Later in his life he stated when
challenged about
apparent contradictions: "It may be so, there is no arguing against facts
and
experiments." This is a common argument to justify belief in religion: such and such a
doctrine
is true because there is no better explanation, it is true because you can't
prove it is
wrong. But the burden of proof is on the proponent of belief, not the
skeptic. Newton
makes this clear. INFERRING "TIS THUS BECAUSE NOT OTHERWISE..." IS A
FALLACY.
9) Frame of Reference will disclose the fallacies in the logic of even
modern
thinkers when they conclude..."'tis thus because not otherwise..." It is a
weakness in
Man to jump to conclusions, and there is an almost irresistible tendency to
philosophize
and make theories to fit the pieces of facts together (as with a puzzle)
first, and find out
later if nature (and society) follows the theoretical pattern. Rash
judgment and the rush
to judgment are the bane of too many otherwise quite capable thinkers and
both lead to the
development of superstitions and even foster an acceptance of the belief in
gods. 10) Newton made many contributions to science after his publication of
Philosophiae
Naturalis Principia Mathematica, first written in Latin. Besides explaining
the motions of
Jupiter, Saturn and Earth in terms of his gravitational theory, he showed
how to find the
masses of Sun and the planets from the mass of Earth. He got a value quite
close to
that which is found by the latest methods; the density of Earth is between
five and six
times that of water. Today we know it is in a ratio of 5.5 to one. He
showed that Earth
is flattened at the poles, as are other planets, and showed the mathematics
describing
the shape which agrees well with the latest measurements. 11) Newton also described "the precession of the equinoxes." Our Earth is
tilted at
an angle of about 66.5 degrees with the plane of its orbit which accounts
for the
occurrence of Summer and Winter as the relative perspective to Sun changes.
However, Earth's axis does not keep precisely parallel to itself, but very
slowly changes
its angle so as to trace a cone in the heavens. It takes nearly 26,000
years to complete
the cone (precession). Newton also calculated the irregularities of Moon's
motion
caused by the pull of Sun and explained that the tides of the sea are due to
the pull of
both Moon and Sun. With all this he did not speculate on the cause of the power of gravity:
"It is
enough that gravity does really exist, and act according to the laws which
we have
explained, and abundantly serves to account for all the motions of the
celestial bodies,
and of our sea." Thus the facts of nature and Universe have no moral
authority and
exist as ontological laws up to the point that these same 'laws' are
refuted by new
experimental data. 12) In 1704 Newton finally published his seminal work: Opticks: or a
Treatise on the
Reflexions, Refractions, Inflexions and Colours of Light. In the second
edition he
wrote: "These Principles I consider not as occult Qualities, supposed to
result from the
specifick Forms of Things, but as general Laws of Nature, by which the
Things
themselves are form'd: their Truth appearing to us by Phaenomena, though
their
Causes be not yet discover'd...To tell us that every Species of Things is
endow'd with
an occult specifick Quality by which it acts and produces manifest Effects
is to tell us
nothing." Newton proved that all colors are produced by mixtures of pure
spectral
colors. The colors of flowers, clothes and paints are called absorption or
subtraction
colors. The apparent color is due to subtraction of colors from the light
of Sun or from
other sources of light, and the apparent colors are those available to be
reflected. A
piece of pure red cloth looks red because it absorbs the whole blue,
green,
yellow, and orange parts of the spectrum of natural light but reflects the
red. 13) The next big advance in physics came in 1905 when Albert Einstein
(1879-1955)
published four papers including his memoirs on special relativity.
According to his
principle of relativity, light should have the same properties for all
observers in uniform
relative motion, and its velocity in a vacuum should therefore be the same
for all
observers. The velocity of light (186,282 miles per second) is constant
and a
maximum in the electromagnetic and the mechanical worlds. Light
would thus
travel with a constant velocity that was independent of the bodies emitting
or receiving
it. In 1916 Einstein published "General Theory of Relativity" in which he
sought to
extend the principle of relativity to frames of reference (and observers) in
all types of
relative motion. The reader is invited to look at other sources to find a detailed
description of
these principles. Einstein maintained that the laws of nature discoverable
by physics
are deterministic. Although the consequences of a physical theory must be
tested
empirically, its axioms are not automatic inferences from experience but are
free
creations of the human mind, which is guided by considerations of a
mathematical
nature. (see verse 36) 14) The strict material nature of Universe found a champion in Hugh Elliot
(1881-1930). He put forth three principles: He was fortunate to have lived in a time when his heretical views were not
the
justification for persecution, imprisonment and death as has been the case
with other
freethinkers in the past.
15) Now, Physics is dominated by Quantum Mechanics which discloses three
paradoxes. First, quantum mechanics proves that motion could not take place
in the
classical way. Instead, things move in a disjointed or discontinuous
manner. They
jumped from one place to another, seemingly without effort and without
bothering to go
between the two places. 16) The second paradox contradicts the view that science is a reasonable,
orderly
process of observing nature and describing what is observed objectively.
The former
view that whatever one observed as being out there - was really out there -
has
changed. Quantum mechanics indicated that what researchers used, the
apparatus, to
observe nature on an atomic scale in a real way creates and determines what
is found.
Even the most basic idea of matter, the concept of a "particle," turns out
to be
misunderstood if one assumes that the particle has properties totally
independent of
the observer. Likewise, what one observes may depend on what one chooses to
observe. 17) The third paradox: despite the natural disorder apparent in many
phenomena,
quantum mechanics establishes that there is an order to Universe. It simply
isn't the
order we expected. Even describing the true order is difficult because it
involves
something more than the physical world. It involves us, our minds, and our
thoughts.
Just how physics and our minds are to be brought together is a controversial
subject.
Our minds may enter into nature in a way we had not imagined possible. "The
thought
that atoms may not exist without observers of atoms is curious, but perhaps
much of
what is taken to be real is mainly determined by thought. Perhaps the
appearance of
the physical world is magical because the orderly processes of science fail
to take the
observer into account. The order of the universe may be the order of our
own minds."
(Fred Alan Wolf, Taking the Quantum Leap, 1981) (see Undecimus Stele:
Agnosticism,
verse 31) 18) "Men whose research is based on shared paradigms are committed to the
same
rules and standards for scientific practice. That commitment and the
apparent
consensus it produces are prerequisites for normal science, i.e. for the
genesis and
continuation of a particular research tradition. . . Acquisition of a paradigm
and of the
more esoteric type of research it permits is a sign of maturity in the
development of any
given scientific field." (Thomas S. Kuhn, The Structure of Scientific
Revolutions, 1962) The Big Bang theory and quantum mechanics are examples of contemporary
paradigms. 19) During recent years radar has become the most important means to study
meteors. Radar can see by day as well as by night, in cloudy weather as
well as in
clear. It was in 1938 that J. A. Pierce of Harvard got the first echoes of
radio signals
from the incandescent trails of meteors. The signals were reflected from
the gases
rather than passing through them. This led to further refinements in the
use of radar
which remained an important military secret during World War II. Stay tuned, there is a huge culture of physics that is interested in tuning
into
Universe for extraneous noise or messages. Nothing intelligible has been
received. 20) In February of 1931 Einstein addressed several hundred students in
Pasadena,
California, and asked why science had brought such little happiness. In war
it had
enabled men to mutilate one another more efficiently and in peace it had
enslaved man
to the machine. "If you want your life's work to be useful to mankind, it
is not enough
that you understand applied science as such. Concern for Man himself must
always
constitute the chief objective of all technological effort, concern for the
big, unsolved
problems of how to organize human work and the distribution of commodities
in such a
manner as to assure that the results of our scientific thinking may be a
blessing to
mankind, and not a curse. . . You feel that this old chap in front of you is
singing an ugly
tune. . ." A wise caution. 21) The conception of the atom has changed dramatically in the twentieth
century.
If atoms are not things, then what are they? Werner Heisenberg answered
that
question in an important way: All classical ideas about the world had to be
abandoned.
Motion could no longer be described in terms of the classical concept of a
thing moving
continuously from one place to another (see verse 4). This idea only
made
sense for large objects; it did not make sense if the 'thing' was
atom-sized. Concepts
are reasonable only when they describe our actual observations rather than
our ideas
about what we think is happening. Since an atom was not seen, it was not a
meaningful concept. 22) We are tempted to peek Physics is concerned about the most infinitesimally small objects and waves
and
about the most dynamically large objects distributed chaotically [influenced
by waves]
around Universe. 24) It is common for consumers to find labels and even warnings on grocery
products and even clothing. Imagine the surprise and confusion if these
product labels
reflected the discoveries of physics during the 20th century. They might
read: HANDLE WITH EXTREME CARE: ATTENTION:
PLEASE NOTE: The center of Milky Way has a complex structure, barely visible through the
interstellar gas and dust that accumulate in the 28,000 light years between
here and
there. Looking with radio waves and with infrared light we see a
chalice-like congress
of rapidly orbiting stars, a pair of jets about 4 light-years long, a stable
ring of orbiting
gas clouds, another ring rushing outward and an array of lacy arcs and
threads
standing 70 light-years high. Dynamic studies indicate a mass in excess of
a million
Suns within three-quarters of a lightyear around the center with only a
hundred
thousand stars visible, the rest of the mass, 900,000 solar masses, could be
involved in
the black hole. The area is engulfed in a powerful electromagnetic field,
like a dynamo.
(see Primus Stele: Heavens - Universe, verse 37) 26) In 1971 it was shown that X-rays coming from Cygnus X-1 were of
irregular
intensity. The source of the X-rays and radio waves were near a visible
star,
HD-226868, about 10,000 light years away, about 1,000 times as far as Sirius
(close
star), and thirty times the mass of Sun. This star was orbiting around
another object
every 5.6 days, but there is no trace of this object. It is considered too
massive to be a
White Dwarf or a Neutron star; neither could be so massive without
collapsing further.
So this was thought to be the first known black hole. Stephen Hawking is one of the masters of black hole psychology, as it were.
Most theorists agree that black holes can explode releasing a massive dose
of X-rays
into inter-galactic space. Part of the convincing force of Hawking's theory
is that it
unites relativity, thermodynamics and quantum mechanics, three otherwise
distinct
fields of science previously not combined in a single set of equations.
". . .It all fitted
together so perfectly that it just had to be right. . .Nature wouldn't have
set up anything
as elegant as that if it were wrong." (Stephen Hawking) Fostering such
'belief
statements' in the scientific community is not very constructive. 27) Neutron star binaries are rare (like true love) in Universe and
difficult to detect
from their electromagnetic radiation. Astronomers have catalogued more than
400
neutron stars (as of 1992) but they have confirmed only four pairs of
orbiting neutron
stars in Milky Way galaxy. From these four, relatively close, we can
calculate how
many neutron stars collide somewhere in Universe every year. Experts
estimate that a
few pair of neutron stars are likely to merge every year within about 650
million
light-years of Earth. (If this were the same frequency of the existence of
life on other
planets and of extra-terrestrial human evolution, it would not be a
surprise.) Binary
neutron stars are a source of gravitational waves whose strength can be
predicted from
fundamental principles of physics. These conditions are ideal for observing
effects
consistent with Einstein's theory of relativity, the orbital period should
be "gradually
decreasing as the system loses energy in the form of gravitational waves."
These
waves can be measured on Earth, and changes can be detected and used to
confirm
the theory. 28) In 1962 when the US Mariner 2 headed toward Venus, near Sun, the probe
ran
into a headwind gusting to 1 million miles an hour. This solar wind is a
continuous flow
of electrons, protons and atomic nuclei. This is part of an expanding solar
corona, the
effects of which are visible in the tails of comets which always point away
from Sun as
they travel their elliptical orbits. The region between Sun and Earth is
filled with 'star
stuff' fragments of solar particles, photons moving at the speed of light
from all visible
sources, a veritable tidal wave of neutrinos, all making up what is called
'plasma.' When Apollo astronauts arrived on Moon, they unrolled banners of aluminum
foil, facing Sun. These were brought back and carefully analyzed revealing
atoms of
hydrogen and helium embedded in the foil--matter discharged as part of the
solar
wind. Solar flares release these particles along with the energy of 10
million hydrogen
bombs. Gas in the explosion often reaches 20 million degrees Celsius, hotter than the
center of Sun. If flares weren't so short-lived, their incredible
temperatures might set
off fusion reactions in Sun's corona. A big explosion there, without the
great mass of
Sun to muffle it, could be a catastrophe for life on Earth. Thus, we are
lucky that solar
flares are brief. There is an 11 year cycle of geomagnetic storms on Earth;
that cycle
being linked to sunspots. There is also a 27 day cycle that occurs for
several months,
coincident with the solar spinning. Sun acts like a strobe light in these
events, with the
'coronal holes' pouring out an extrapowerful stream of solar wind like a
focused
lighthouse beacon. 29) I remember the rare occurrence of the Northern Lights visible in Oregon.
As a
child I stared in fascination as I still do now on such rare occasions.
These have been
explained by geophysicist Syun-Ichi Akasofu (University of Alaska) who left
Japan for
Alaska so he could devote his life to the study of the aurora. The solar
wind, plasma,
includes the motion of electrons and solar magnetism that create an electric
current.
When these two magnetic fields combine in a complex way they become a
natural
electric generator creating as much as 1 million megawatts. This power
accelerates
some particles of solar wind that manage to penetrate Earth's magnetic force
field, and
these particles hurtle toward Earth. They spiral toward the polar regions
(both north
and south) following the lines of Earth's magnetic field shaped like
funnels. As the solar
particles collide with atoms and molecules in our upper atmosphere, these
atmospheric
particles are ionized -- they lose electrons -- and emit light. Low energy
solar particles
reach an altitude of about 150 miles and when they hit oxygen atoms they
emit red
light. High energy particles penetrate farther, as low as 60 or even 50
miles and they
strike oxygen harder and give off a pale green light. From below on Earth
we see
rippling arcs and sheets, the aurora; from above, satellites see a halo
sitting on Earth
as if to beatify our existence. "Our planet is a giant television tube,"
says professor
Akasofu. 30) What is life? It is a basic tenet of physics that phenomenon in
Universe tend to
run downhill, from order to disorder and at last to chaos. This principle
is known as the
Second Law of Thermodynamics. It is known to the public as the concept
'entropy.' It
is sort of incorporated into a famous sociological principle: Murphy's Law,
"Anything that can
go wrong, will." So how is life sustained? Life is a huge and intricate
molecular
contraption that manages for a while to reverse the general trend, at least
as long as it
takes to replicate itself. A living system is a triumph of order, and in a
Universe that is
otherwise running downhill, life is matter that goes against the flow (thanks to Earth's open system fed by Sun). Each
little
creature's victory of self-preservation is achieved at such great expense of
energy that
the inanimate world deteriorates slightly faster in consequence of life's
presence. Each
life must eventually come to an end, Universe declines eventually, but
only to possibly give
rise to new beginnings and potentially new life. (We can only imagine this
process of
regeneration, we won't be around to see it.)
31) An important theorist in the physics of Universe is Andrei Linde (from
Russia).
Linde's concept involves beginning with an absolute minimum of initial
conditions -- the
state we call chaos. "One just considers all possible kinds and values of
scalar fields in
the early universe and then checks to see if any of them leads to inflation.
Those
places where inflation does not occur remain small. Those domains where
inflation
takes place become exponentially large and dominate the total volume of the
universe."
This may require a universe precedent to ours, and it implies the existence of
countless
other universes. Linde's is a theory of a multiverse. 32) Come back to Earth for a moment. For an aquatic plant such as a seaweed
to
evolve into a land plant of any considerable size, it would need to develop
strength and
stiffness to overcome the pull of gravity and replace the buoyancy of water.
At the
same time, it would have to develop some way of preventing loss of water
from its
tissues to the air. A stranded seaweed, without this protection, soon
shrivels and
hardens. This is the nature of the physics and engineering problems
associated with
the first formation of plants on Earth's surface. In widely scattered parts of the southern hemisphere live the last
remnants --
three species -- of the most ancient group of true land plants. The
psilotales, are the
size of ferns but lack such fern-like refinements as roots and well
developed leaves.
Their narrow, aerial stems which spring upright from creeping underground
stems, are
well adapted for life out of water. These contain woody tubes that conduct
water from
undergournd to all parts of the plant. Other vessels conduct liquid
foodstuffs, and the
presence of these specialized vessels explains the term vascular plants, of
which the
psilotales are the oldest and most primitive survivors. Remnants of this
plant survive in
the tropics; in Hawaii it colonizes lava flows and is known as the Moa
plant. It may be that the liverwort (closely related to mosses) is a transition
species
between water dependent plants and land-lubbing plants. Liverworts need to
live partly
submerged, as mosses need to live in moist climates. The thallus, plant
body, of the
liverwort consists of irregularly-shaped green lobes, which are held to the
bank it grows
on by rootlike rhizoids, simpler than roots. The liverwort reproduces
itself by the
fertilization of an egg with a motile sperm that swims to the egg, thus it
needs water in
the same way seaweed does. In these primitive developments, one can see the
laws of
physics and chemistry coming together to produce a complex and successful
Nature.
33) The gyroscope Earth we inhabit is traveling a bumpy road, so to speak.
It
wobbles like a top beginning to slow. One of the most prominent of Earth's
wobbles is
a repeated 433-day lurch known as the Chandler wobble. This wobble is
presumably
reinforced by pressure changes on the ocean floor. Richard Gross of NASA,
suggested that two-thirds of the wobble effect is due to oceanic pressure
the remaining
third comes from pressure changes in the atmosphere. The wobble probably
occurs
because Earth's crust is asymmetrical and lumpy. As a result, the weight of
the oceans
and atmosphere is distributed unevenly, creating pressure differentials that
nudge the
spin of Earth just a small percentage of its motion. Understanding the
source of the
Chandler wobble could enable NASA to measure it and help position
spacecraft.
(Popular Science, December 2000)
34) Just when we thought there were laws of physics that limited what living
organisms could withstand, we discover a new microbe that breaks all those
rules. A
new organism called 'nanobes' has been discovered deep (three miles) below
the
surface of the Australian landscape. Found in solid rock, surviving
temperatures as
high as 338 degrees Fahrenheit, seen only with an electron microscope
magnifying
them 20,000 times, they are smaller than any cell, fungus or bacterium ever
found on
Earth. They are measured at between 20-150 nanometers in length and contain
DNA
as well as distinct cell membranes, grow spontaneously, and are packed with
carbon,
nitrogen and oxygen, essential for life. These 'creatures' not only degrade
toxic
organic compounds but are also capable of producing antibiotics, enzymes and
biologically friendly pigments to stain larger microbes. (Discover,
January, 2001)
35) "The year 2000 was the most exciting for cosmology since the 1930's"
says Max
Tegmark, a Princeton physicist. New experiments confirm the theory of
inflation which
casts a new light on the Big Bang theory. In 1992 NASA's Cosmic Background
Explorer satellite confirmed the echo of the Big Bang, a one-thousandth of a
percent of
variation in the brightness of the cosmic background radiation. Not unlike
heat waves
rising from hot pavement on a hot summer day distort the horizon. In 1999 Saul Perlmutter and a team at Lawrence Berkeley Lab, California, and
another
team at Harvard University Center for Astrophysics have calculated the
expansion of
Universe is actually increasing. They looked at a group of 10,000 galaxies
every few
days to find a few newborn supernovae, these occur in each galaxy at a rate
of about
two each thousand years, but randomly. Follow-up pictures reveal the color
of the
fading supernova flash that lasts a week. Comparing 40 such events, (they
had seen
82 by the end of 2000) they found "The expansion of the universe is speeding
up." In order for Universe to expand the total mass must be greater than the
gravitational force that would tend to pull it back into its presumptive
center. Using the
best current estimates of the mass density of Universe, Perlmutter's team
calculated
how much dark energy was needed to account for the observed acceleration.
They
found that they needed a lot -- about 60 percent of the critical density,
which is the
same extra mass needed to make the Universe flat. Recent results from three
telescopes measuring microwave background 'noise' confirm that Universe is
flat. But
if this is the case, where is and what is all the dark energy and matter
that makes it so.
They are trying again to weigh the oceans of dark matter by observing the
warp and
distortion of light as it passes from far distant galaxies to our point of
observation. If
they succeed in measuring this matter, the standard Big Bang theory will
have to be
changed. "No current theory, not even inflation, predicts the presence of
dark energy"
so stay tuned for a new theory to describe Universe. (www.popsci.com,

36) The reader will notice that in this discussion of physics there is no
mention of
mechanical aspects such as the details of leverage, pressure, temperature
exchange or
hydraulics. None of these engineering details have much to do with religion
or ethics,
except as these testify against the claims of miracles, such as parting of
the Red Sea
by Moses, or turning water into wine. These fanciful stories, to the extent
that they
have any incidental historical relevance, tend to be distorted by oral
histories and
exaggerated in the retelling. If someone begins a discussion about ethics
or morality
with a reference to miracles, prophecy or knowledge from extra-terrestrial
beings, it is
reasonably certain that their information can be suspect to the extent that
it violates the
physical laws of nature, mechanics, etc. If these physical laws were in any
way arbitrary
and could be suspended by the exercise of some mental power, such as
telepathy, or a
god, someone would have taken out a patent and made a fortune by its use. A
religious faith that depends in any way on the suspension of the laws of physics ought
to be discarded in favor of a simpler belief system, or none at all.
37) When you go to the ocean, you had better appreciate it while it lasts.
James F.
Kasting of Penn State U., predicts that the oceans may evaporate much
earlier than
previously predicted based on the expected evolution of Sun. Sun, now 4.5
billion
years old, is about halfway to becoming a red giant. The thermonuclear
furnace of Sun
consumes hydrogen, but once this is complete it will begin to use Helium and
become
hotter. This is a gradual process, and as soon as you get a 10% increase in
solar
luminosity, that's enough to drive water into the stratosphere where the
molecules
brake apart under the more intense radiation. Eventually Earth would look
like Mars,
and this could be as soon as 1 billion years from now. 38) The energy coming from Sun exhibits the rule of The Special Theory of
Relativity
expressed in the now famous equation, E = mc2. "The equation
expresses
the convertibility of matter into energy, and vice versa. It extends the
law of the
conservation of energy into a law of conservation of energy and mass that
can be
neither created nor destroyed. . . 'E' stands for the energy equivalent of the
mass 'm'. . .'c'
is the velocity of light. . . The complete conversion of one gram of mass into
energy
releases. . .a thousand tons of TNT. Enormous energy resources are contained
in tiny
amounts of matter, if only we knew how to extract the energy." (Carl Sagan,
Broca's
Brain, 1974)
"(1) the laws of the universe are uniform, and while the universe may
appear
disorderly, careful scrutiny by science reveals that these universal laws
are to be
obeyed;
He stated further that "An act of consciousness or mental process is a
thing of
which we are immediately and indubitably aware: . . .But that it differs in any
sort of way
from a material process, that is to say, from the ordinary transformations
of matter and
energy, is a belief which I very strenuously deny. . . There exists no kind of
spiritual
substance or entity of a different nature from that of which matter is
composed. . . there
are not two kinds of fundamental existence, material and spiritual, but one
kind only. . ."
(2) teleology is a myth, for there is no such thing as a purpose to the
universe
and all events are due to the interaction of matter in motion;
(3) all forms of existence must have some kind of palpable material
characteristics and qualities."Crystal Ball
23) We have moved a long way from the original discovery in 1802 (see Primus
Stele: Heavens, verse 26) leading to the spectroscope to where we are today,
using
basically the same technology. In January, 2001, the National Aeronautic
and Space
Administration, NASA, planned to launch a High Energy Solar Spectroscopic
Imager
(HESSI) to explore the basic physics of particle acceleration and energy
release in
solar flares. This launch and satellite will cost $40 million dollars to
develop and
deploy.

If we do this magic
Would it be wise to know?
If we perceived our Fate
What need is there to think?
Would advanced knowledge help
Create virtue in Man?
What credit can we take
If life is prearranged?
Singing music soothes us
But is not a sacred act
If life is like a song,
Verses known, sung in time.
Where would be the glory?
What challenge is there then?
What test is harmony
When words rhyme so easily?
Can each soul grow and bloom
When led by fate alone?
The force of nature then
Would be a tyranny.
So with Love, as Virtue
Constrained it disappears.
Which coincidences of science
Do we see as design?
Which part of life is chance
How can we be so sure?
This is my wish: to thrive
Challenging and blessed
Forever by freedom's effort --
I seek the art in life.
What other proof is there?
Except I wrote this poem.
(IJ - 1995)
CAUTION:
25) A neutron star is the last resort for a sun which might condense even
further into
what has been identified as a black hole (something of a toxic waste
disposal
receptacle for spent nuclear fusion reactors -- old stars). A black hole is
where matter
is converted into energy at an astounding rate. If a large sun implodes to
a sufficiently
small and dense state its gravity will overwhelm all remaining forces that
might prop it
up and it will disappear from view, taking all light in its vicinity into it
like a trash
compactor. The resulting black hole is surrounded by an oblate zone, the
event
horizon, into which nothing can venture with any hope of return. As
suggested, Milky
Way may have a black hole as its central attraction.
The Mass of This Product Contains the Energy Equivalent of 85 Million Tons

Some Quantum Physics Theories Suggest That When the Consumer Is Not Directly Observing This Product, It May Cease to Exist or Will Exist Only
in a Vague and Undetermined State. (Susan Hewitt and Edward Subitzky, The Journal of Irreproducible Results, 1991)"When I was in high school, I developed a nice theory of how extrasensory
perception might work. But then I learned that it violated the special
theory of relativity.
I realized that unless I learn physics I may come up with all sorts of ideas
that will sound
nice, but always I will be talking nonsense. . . It is a very dangerous
feeling, this feeling
that you're not totally secure in what you're doing. But it makes life so
exciting."
In Linde's cosmological picture, there are many events similar to the Big
Bang
that ballooned Universe to its enormous present size. "In essence, one
inflationary
universe sprouts other inflationary bubbles, which in turn produce other
inflationary
bubbles. . ." The multiverse contains innumerable bubbles like the one in
which we find
ourselves, and other regions even larger, and still other regions in which
inflation is
going on right now--a theory of eternal inflation. "The classical big
bang theory is
dead. . . [it is] a very interesting theory that we must study, but the
original big bang is
somewhere in the distant past. . . The evolution of the universe as a whole has
no end,
and it may have had no beginning. . ."
